Russia installs S-300 missile system at Tartus base in Syria

Russia claims it has installed an S-300 missile system at a naval base in the Syrian port city of Tartus, amid rising tensions between Moscow and Washington over the five-year conflict in the country. This is the first time Russia has deployed such a system outside its territory. Earlier, Washington said it was suspending talks with Moscow, that had been aimed at reviving a ceasefire deal earlier brokered by the two countries.
